Yuav ua li cas rau pob tw-fusion weld PE kav

(1) Ua ntej kub-kub, txhuam qhov kawg ntawm cov yeeb nkab PE, txhuam cov oxide txheej ntawm qhov chaw, thiab tom qab ntawd siv cov phuam so los so cov plua plav sab hauv.

(2) Nrhiav cov pob qij txha thiab cov nplhaib hlau uas muaj qhov sib npaug ntawm cov yeeb nkab PE, tig lub tshuab kub yaj kom preheat, thiab thaum tshav kub txaus, muab cov yeeb nkab PE thiab cov sib koom ua ke rau tib lub sijhawm.

(3) Tshem tawm tom qab ib feeb los yog li ntawd, tam sim ntawd ntxig lub connector ntawm lub nozzle, thiab kho nws nrog lub nplhaib hlau.

Dab tsi yog qhov zoo ntawm HDPE kav?

PE yeeb nkab muaj zog corrosion kuj. Txawm hais tias nws yog faus rau hauv av lossis raug huab cua, nws tuaj yeem tiv taus lub hnub thiab nag thiab tsis yooj yim rau kev puas tsuaj; qhov cuam tshuam tsis kam thiab tawg tsis kam ntawm cov yeeb nkab zoo li no kuj zoo heev. , ruaj khov thiab txhim khu kev qha, zoo heev rau siv.
